Installation

• The system manufacturer or the machine builder is responsi-
ble that the inherent installation and security informations are
harmonised with the valid standard and guidelines (DIN EN
292/294/60529/ Draft standard N107-2:2003 (E) ).
• The following applies for all fans:
- Do not install without adequat support. Mounting surfaces
must be even.
• We recommend to monunt the included bracket for fixing the
fan
• Systemair Tube fan RUK 315 44 are not delivered with con-
nection box. Contructor is responsible for correct installation
of the fan
• Controllers RTRD and motor protection switch UEK are not
allowed to be installed in the hazardons area.
Under maintenance of the materials mating, the following mini-
mum gap must be fulfilled: between rotating and stationary parts,
the minimum gap cannot be smaller than 1 % of the relevant
contact diameter, but not less than 2 mm in the axial or radial
directions, and must not amount to more than 20 mm.
- Fans without wire support guards or without inlet rings:
for mounting on static motor flange.
Use screws of class 8.8 and secure with Loctite.
Starting torques allowed: M6 = 9.5 Nm; M8 = 23 Nm;
- Certain operating points/speeds may not be run during
selfresonance of the attached components. The verification of
self-resonance is to be carried out by the system constructor
during start-up operation
- For motors mounted with shaft vertical, the drain hole under-
neath the shaft must be open.
- Electrical connection corresponding to connection diagram on
stator or on fan housing
- Secure motor connection cable with cable fasteners or cable
clips
- For operation under extreme conditions (e.g. damp operat-
ing environment) attach a water drain sleeve or use a sealing
compound.
- Upstream or downstream components or components which
are located direct in the air flow may not have any unprotected
aluminium or steel surfaces. They must be painted or coated
with plastic which must be min-cutting value 2 according to
DIN EN ISO 2409, in order to prevent an aluminothermic reac-
tion.
- If hazards from lightning strikes have been ascertained, the
system must be protected through the use of suitable lightning
protection measures.
- Systems must have a sufficient distance from transmitting in-
stallations or be protected through suitable shielding.

Operating Conditions

• Operate the fan with the voltages and frequencies given on the
fan type plate (sticker). The operation with the voltages / switch-
ing frequencies given on the type plate is allowed but not effi
cient. Exceeding the stamped nominal current by speed con-
trol by reduction in voltage is permissible by the value shown in
the Conformity Certificate (...%).
• Motor cut-out is effected by thermistors DIN 44082-M con-
nected to a tripping mechanism with the test certification [03
ATEX 3045]. The thermistor reacts upon all faults, e.g. deviat-
ing temperature of the transfer medium or operation in a not
permitted area of the fan characteristic curve. Attention: Use of
a frequency inverter is not allowed
• Switching frequency:
-The fan is rated for S1 continuous operation.
- Controls must not allow extreme switching operation.
• The type plate contains the electrical value for the optimal
cooled motor approved by the EC Certificate of Conformity.
In order to achieve favourable fan control response, the voltage
for motors with speed control specified in the certificate may be
larger than the fan´s rated voltage (sticker).
Commissioning
• Before initial operation, check the following:
- Installation and electrical connection have been properly com-
pleted.
- Safety equipment is in place ( Contact protection).
- All leftover installation materials and other foreign materials
have been removed from the fan cavity.
- The impeller must not drag against non-moving parts ( igni-
tion sparks!).
- Protective conductor and external earthing conductor have
been connected.
- Thermistor and triggering device have been properly installed
and are operational.
- Cable gland is sealed (see "Installation").
- Installation position and the arrangement of drain holes cor-
respond to each other.
- Connection data complies with the specifications on the type
plate.
• Commissioning may only take place if all safety instructions
have been checked and danger can be excluded.
- Check sense of rotation/air feed direction definition of the
sense of rotation according to picture
- See to smooth running Intensive vibrations due to uneven run-
ning (out-of-balance) e.g. because of damage intransit or im-
proper handling may lead to outage, if applicable, have the
imbalance checked.
- All conductive attachment and accessory parts must be
grounded.
- During erection/start-up operation, the ambient temperature,
air humidity, environmental contamination, and corrosion
through the surroun-ding atmosphere must be taken into con-
sideration.

Maintenance, service

• Due to the selection of bearings with "lifetime lubrication" (spe-
cial grease), the external rotor motor is maintenance-free.
• Upon signs of wear or latest after 40,000 h, a bearing ex-
change is required.
• Ask for our Maintenance Guide or contact our Repair Depart-
ment (special tools may be required!).
• Replace bearings only with original parts (Ziehl-Abegg spe-
cialgrease). The following points must be observed when per-
forming any maintenance or service operation:
- Rotor or mounted components have come to a standstill!
- Power supply interrupted and secured against restoration!
- Observe personnel safety regulations!
• The system constructor must enable easy access for cleaning
and inspection work.
• Regular cleaning helps prevent motor unbalance.
- Under no circumstances is a high-pressure cleaner ("steam
jet") to be employed!
• Take note of abnormal operating noise!
• For all other defects (e.g. cable and wire lead-ins, windings and
cables), please contact our repair department maintenance or
service operation:
- Rotor or mounted components have come to a standstill!
- Power supply interrupted and secured against restoration!
- Observe personnel safety regulations!
• The system constructor must enable easy access for cleaning
and inspection work.
• Regular cleaning helps prevent motor unbalance.
- Under no circumstances is a high-pressure cleaner ("steam
